 a processor that performs the signal processing of the left eye image and the right eye image which are imaged by the camera head; and 
 an output that outputs the left eye image and the right eye image on which the signal processing is performed to a monitor, the left eye image and the right eye image being misaligned when projecting a three-dimensional image on the monitor, 
 wherein the processor adjusts an extraction position of at least one of the left eye image and the right eye image in accordance with a user operation based on the left eye image and the right eye image which are displayed on the monitor, to correct a projection of the three-dimensional image on the monitor, 
 the processor saves an adjustment result of the extraction position of the at least one of the left eye image and the right eye image in a memory, and 
 the processor is configured to adjust an extraction position of both of the left eye image and the right eye image which are imaged by the camera head in at least one of a horizontal direction or a vertical direction in accordance with the user operation. 
 
     
     
       2. The image processing apparatus of  claim 1 ,
 wherein the processor adjusts the extraction position in the horizontal direction of at least one of the left eye image and the right eye image which are imaged by the camera head in accordance with the user operation. 
 
     
     
       3. The image processing apparatus of  claim 1 ,
 wherein the processor adjusts the extraction position in the vertical direction of at least one of the left eye image and the right eye image which are imaged by the camera head in accordance with the user operation. 
 
     
     
       4. The image processing apparatus of  claim 1 ,
 wherein the processor adjusts the extraction position both in the horizontal direction or in the vertical direction of the left eye image and the right eye image which are imaged by the camera head in accordance with the user operation. 
 
     
     
       5. The image processing apparatus of  claim 1 ,
 wherein the processor determines a distance from the optical instrument to the target site based on the parallax appearing in the left eye image and the right eye image which are imaged by the camera head in a 3D mode, and 
 the output outputs information on the distance to the monitor together with the left eye image and the right eye image on which the signal processing is performed. 
 
     
     
       6. The image processing apparatus of  claim 5 ,
 wherein the output interrupts the output of the information on the distance to the monitor in response to switching from the 3D mode to a 2D mode. 
 
     
     
       7. A camera apparatus comprising:
 a camera head that is capable of imaging a left eye image and a right eye image, the left eye image and the right eye image having parallax on one screen based on light at a target site incident on an optical instrument; 
 a processor that performs the signal processing of the left eye image and the right eye image which are imaged by the camera head; and 
 an output that outputs the left eye image and the right eye image on which the signal processing is performed to a monitor, the left eye image and the right eye image being misaligned when projecting a three-dimensional image on the monitor, 
 wherein the processor adjusts an extraction position of at least one of the left eye image and the right eye image in accordance with a user operation based on the left eye image and the right eye image which are displayed on the monitor, to correct a projection of the three-dimensional image on the monitor, 
 the processor saves an adjustment result of the extraction position of the at least one of the left eye image and the right eye image in a memory, and 
 the processor is configured to adjust the extraction position of both of the left eye image and the right eye image which are imaged by the camera head in at least one of a horizontal direction or a vertical direction in accordance with the user operation. 
 
     
     
       8. An image processing method in which an image processing apparatus is connected to a camera head, the camera head being capable of imaging a left eye image and a right eye image, the left eye image and the right eye image having parallax on one screen based on light at a target site incident on an optical instrument is used, the image processing method comprising:
